Abstract/OtherAbstract:
13C NMR integral areas and spin-lattice relaxation times (T1's) of a series of amino acids were determined at different concentrations. It was found that the spin-lattice relaxation times were markedly reduced in 3 M magnesium chloride resulting in the integral area being proportional to the number of carbon atoms producing each particular signal, with a reliability in excess of 95%. Magnesium chloride is proposed as a 13C NMR relaxation agent for amino acids.
